(4-6x)/0.01-6.5=(0.03-3x)/0.03-7.5
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
3/x-1=4/x 6/x+1=x+5/x(x+1)
6/(x+1)=(x+5)/[x(x+1)] (3-x)/(x-4)+1/(4-x)=1 2/(1+x)-3/(1-x)
1、x*(x+3)*(x+6)*(x+9)=68040 2、x*(x+1)*(x+2)*(x+3)*(x+4)=5544
解方程:-x(x+6)=3x-(x-3)(x+4)
5x-3(2x+1)=6x-4(5-3x)求x
3x(2x+3)=4x+6
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
X-(X/2)+(X/3)-(X/4)+(X/5)-(X/6)=1
5(x²+x-3)-4x(6+x)+x(-x+4)=0
